A few years ago there was a show called Three Sheets. This guy traveled around the world drinking, learning the cultures and then their hangover cures. I think you can still find it on Hulu.

On a similar note-

Dave Attel used to have a show on Comedy Central about 10 years ago called 'Insomniac' that was pretty effin' funny. He used to drink his face off nearly every episode. That was probably my favorite non-scripted show ever.
